Problems solved by technology

[0004] However, if figure 2 As shown, when the flexible touch display device 100 is in a bent state, the distance between the first touch electrode 21 and the second touch electrode 22 will change, so that the first touch electrode 21 and the second touch electrode The capacitance value between the touch electrodes 22 also changes accordingly, which makes the touch chip misjudge the touch position
[0005] Therefore, there is a need to develop a new flexible touch display device to solve the technical problem of misjudgment of the touch position caused by the change of the capacitance value between the touch electrodes at the bend of the existing flexible touch display device when it is bent.

Abstract

The disclosure discloses a flexible touch display device, which includes a flexible display panel, several bridge points, several sensing electrodes, a first insulating layer and several touch electrodes. The bridge points and the sensing electrodes are respectively arranged in the display area and the peripheral area of ​​the flexible display panel. The first insulating layer covers the bridge points, the sensing electrodes and the flexible display panel. The first insulating layer is provided with several through holes in the display area, so that two opposite side parts of each bridge point are exposed. The touch electrode is arranged on the first insulating layer in the display area, and is electrically connected to the bridge point through the through hole to form a metal grid structure. The sensing electrodes are used to sense the bending position and bending degree of the flexible touch display device, so as to compensate and correct the touch position sensed by the touch electrodes at the bending position.

Description

technical field [0001] The disclosure relates to the field of display technology, in particular to a flexible touch display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display panels have the advantages of thinness, active light emission, fast response, large viewing angle, wide color gamut, high brightness, low power consumption and flexibility, etc., and become a display panel technology. in the mainstream. A flexible touch display device that combines organic light emitting diode display panels with a touch structure is the focus of research and development in the industry today. [0003] see figure 1 , the current flexible touch display device 100 includes an organic light emitting diode display panel 10 and a plurality of first touch electrodes 21 and a plurality of second touch electrodes 22 disposed on the organic light emitting diode display panel 10 . The plurality of first touch electrodes 21 and the plurality of second touch electr...
